Abstract

The invention discloses an inner rotor motor wave-shaped friction transmission self-adaption automatic variable speed drive assembly of an electric motor car. The inner rotor motor wave-shaped friction transmission self-adaption automatic variable speed drive assembly comprises an inner rotor drive motor, a box body and a transmission shaft and further comprises a slow gear transmission mechanism and a mechanical intelligent self-adaption variable speed assembly which is arranged on the transmission shaft. A wave-shaped friction surface friction transmission pair is adopted for the friction surface of a drive friction disc and the friction surface of a driven friction disc of the mechanical intelligent self-adaption variable speed assembly. A separation and combination structure is formed through the friction discs, and the automatic variable speed drive assembly has the advantages of being flexible in reaction and small in axial size; meanwhile, the structure that the radial sections of the friction surfaces are in a wave shape, and annular protrusions and annular grooves are embedded to one another is adopted, joint of the friction surfaces is scattered, guarantee of the coaxiality of the drive friction disc and the driven friction disc is facilitated, increase of the friction surfaces is further facilitated, and it is guaranteed that good transmission is kept under the condition of limited elastic force; guarantee of sensitivity of separation and combination is further facilitated, transmission accuracy is improved, and the automatic variable speed drive assembly is applicable to the field of electric vehicles.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to an electric motorcycle inner rotor motor wave-shaped friction transmission adaptive automatic variable speed drive assembly. Background technique [0002] In the prior art, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current control speed through a speed control handle or an accelerator pedal, or use a manual mechanical automatic transmission mechanism to realize speed change. The operation of the handle or the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. [0003] In motor vehicles, when the rider does not know the driving resistance, the speed change device is only operated and controlled based on experience, which inevitably has the following problems: 1. When starting, g...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a side-mounted self-adaptive automatic transmission with wave-shaped friction transmission, which can not only adapt to the change of driving resistance without cutting off the driving force, but also automatically shift and change gears, and solve the problem of torque-rotational speed. Small changes cannot meet the problem of road use under complex conditions; long-term operation can still ensure stable support, reduce operating noise, ensure operating comfort and improve transmission efficiency, thereby reducing energy consumption; change the stroke of the axial joint surface of the fast and slow gear engagement and separation mechanism In the long-term current situation, the separation and engagement are fast and thorough, which is conducive to improving the transmission accuracy. After a long period of use, the overall shape and position tolerance will still be guaranteed, thereby ensuring the stability of the transmission.
